What should a student check when answering a question on use logarithmic graphs to estimate parameters in relationships…?.
- A.F6: connect the result back to the original question
- B.Use any familiar GCSE calculation even if it ignores Use logarithmic graphs to estimate parameters in relationships…
- C.Write only the final answer without showing the mathematical method
- D.Change the notation or restrictions to make the algebra look simpler
Model answer
What a good answer should say
- The correct answer is F6: connect the result back to the original question.
- This option is best because link the algebraic feature to the corresponding graph feature, then checks that the notation, restrictions and conclusion match the AQA A-level Mathematics objective.
This answer is tied to the objective: F6 Use logarithmic graphs to estimate parameters in relationships of the form y = ax^n and y = kb^x, given data for x and y..
Explanation
Why this works
Use the explanation to connect the worked answer back to F6 Use logarithmic graphs to estimate parameters in relationships of the form y = ax^n and y = kb^x, given data for x and y..
F6: connect the result back to the original question is the correct option. It directly supports use logarithmic graphs to estimate parameters in relationships… by requiring the student to link the algebraic feature to the corresponding graph feature.
The other options are weaker because they hide the reasoning, ignore restrictions, or use a generic calculation that may not fit the objective.
Maths method check
- Topic focus: Pure Mathematics.
- Question style: practice.
- Reasoning demand: analysis.
- Check the operation, notation, units, and final answer form against the question before moving on.
